DEVICE FOR REFINISHING AXLES, CRANK-SHAPES, 826.

Specification of Letters Patent.

Patented July 6, 1920.

Application filed December 26, 1919. Serial No. 347.632.

To all whom it may concern:

Be it known that I, GEORGE H. TABER, a citizen of the United States ofAmerica, and a resident of Binghamton, in the county of Broome and Stateof New York, have invented certain new and useful Improvements inDevices for Refinishing Axles, Crank-Shafts, &c., of which the followingis a specification.

This invention relates to an improvement in a device for re-finishingthe surfaces of shafting, axles, crank shaft bearings, etc, and theobject of the invention is to provide a device of this kind which willbe simple in construction, effective, and convenient in use.

The invention consists in the construction and arrangement of partshereinafter more particularly described and then definitely claimed.

In the drawings accompanying and forming part hereof:

Figure 1 is a perspective view of my in vention.

Fig. 2 is a vertical transverse section of the same.

Fig. 3 is a perspective view of the sliding carriage detached.

Referring now to the details of the drawings by numerals: 1 and 2designate two 0ppositely disposed frame members preferably of the shapeillustrated in Fig. 1. The lower frame member 1 is provided with twoupwardly projecting lugs 3 and 4 adapted to receive and support twothreaded rods 6 and 8, these rods being firmly secured in the lugs 3 and1-. as shown. The bottom frame lfbetween the lugs 3 and 4-, is providedwith a way or guide 1% upon which is slidably supported a longitudinallymovable carriage 16, a screw 18 being employed to hold this carriageupon its way or-guide le the carriage 16 having a longitudinal slot- 20permitting movement on the aforesaid way or guide 14-. Any desirableform of cutting instrument or file 22 is secured to this carriage 16 soas to move therewith. An adjusting screw or bolt 24': is provided whichis threaded through the lug 3 and bears upon the end of the carriage 16so that, when said bolt 24 is screwed into the lug 3, it will pressagainst the carriage 1d and move it along its way 1 f until it reachesthe end of its movement.

The aforesaid upper frame member 2 is provided with two bosses 26 and 28which slip over the aforesaid threaded rods 6 and 8 and are capable ofmovingup and down on said rods, wing nuts 30 and 32 being provided onsaid threaded rods, over said bosses 26 and'28, for the purpose offorcing the upper frame member 2 toward the lower frame member 1, in amanner readily understood from the drawings.

Secured to the under side of the upper frame member is a block 34 ofinverted V- shape which is arranged to hold the shaft properly locatedduring the process of refinishing the untrue surface. This inverted Vblock 34 preferably is provided with two recesses 36 and 38 which arefor the purpose of holding thick pieces of felt 39, the felts being flatand of sufficient thickness to fit in the recesses 36 and 38 wherebythey are more easily held in position. The duty of the felt is toprevent the filings from embedding in the V block, thereby resulting intearing or cutting the shaft while in operation.

Each of the frames 1 and 2 is provided with an outwardly extending lug,these lugs being designated by the numbers 4:0 and 42. The purpose ofthese lugs is to receive a piece of pipe to act as a handle whennecessary.

In the operation of the device, the adjusting screw or bolt 24 may beoperated, as occasion requires, to bring a new part of the file 22 inplace, thus eliminating the necessity ofmany removals of the file duringthe process of truing up the surface of the shaft being operated upon,it being understood that the feed screw causes the. clean part of thefile to engage with the shaft surface being filed. if the device shouldbe turned in the wrong direction, the carriage 16 will automaticallyslide along its way or guide 14 and thus give warning to the operatorthat the device is being turned in the wrong direction.

What I claim as my invention is:

1. In a dev'ce of the character described, two frame members adjustabletoward each other, one of said members having a clamping member and theother a sliding carriage provided with a cutting tool, substantially asdescribed.

2. In a device of the character described, two frame members adjustabletoward each other, one of said members having a clamp ing member and theother a sliding carriage provided with a cutting tool, and a screw orbolt for moving said carriage and its tool to presents. new part of thetool to the work, 5 substantially as described.

3. In a device of the character described,

two frame members, one having screw rods projecting therefrom and theotherhaving parts sliding over said screw rods, nuts 011 said screw rodsfor moving one of said frame members toward the other to clamp the work,a carriage on one of said members provided with a tool, and a screw orbolt for adjusting said carriage and its tool, substantially asdescribed.

4; In a device of the character described,

' two frame members adjustable toward each other, one of 'said'membershaving a 'V- shaped clamping member provided with oppositely disposedrecesses, and felt brushes located in said, recesses projecting towardeach other, substantially as described.

' 5. In adevice of the character described, two frame members adjustabletoward each other, one of said members having a V- shaped clampingmember and the other an adjustable sliding carriage provided with acutting tool, and felt brushes carried by said V'shaped clamping member.

6. In a device of the character described, two frame members adjustabletoward each other, oneof said members having a clamping member and theother a sliding carriage provided with a cutting tool, and a screw orbolt for moving said carriage and its tool to present a. new part of thetool to the work, said carriage being free to slide away from said screwor bolt if the device is turned in the wrong direction, substantially asdescribed. j.

7 In a device of the character described, two frame members adjustabletoward each other, one of said frame members having a 'V-shaped clampingmember and the other a guideway, a carriage slidable on said guide- .wayand provided with a tool, and a screw in the wrong direction,substantially as described.

9. In a device ofthe character-described, two frame members adjustabletoward each other, one of said members'having a clamping member and theotherasliding carriage provided with a cutting tool, each of said framemembers having a lug to receive a pipe, substantially as described.

10. In a device of the character described, two frame members, onehaving two bosses projecting therefrom, and provided with a guideway,screw rods projecting from said bosses, the other frame member'having aV shaped clamping member located over said uidewa'y, a carriageslidableon said guideway under said V shaped clamping member, ascrew passingthrough the end of the frameand co-acting with said carriage to move thecarriage and its tool on said guideway to present a new part of the toolto the work, and nuts on said screw rods for moving the upper framemember and its V- shaped clamping member toward the carriage and itstool, substantially as described. In testimony whereof I ailix mysignature in presence of two witnesses.
